Question

Find the slope and y‐intercept.

3 y – 9 x – 12 = 0

Answer 1

The equation

3y – 9x – 12   =   0

Write the above equation in the form of y = mx /= c

Wher "m" is slope and "c" is y -intercept

3y   =   9x + 12

y   =   (9x + 12) / 3

y   =   (9x)/3 + (12) / 3

y   =   3x + 4

Compare above equation with y = mx + c

The slope m = 3

And the y - intercept c = 4.
